Which vehicle? im sure they vary VB-VZ had 12x1.5mm VE-VF had 14x1.5mm I had VF wheels on a VS and had to get special wheel nuts so they didn't come loose. They were chrome ones which last 6mths before they looked rust and crappy
VE-VF had 14x1.5mm These are the right ones? https://www.ebay.com.au/itm/Gorilla...986920&hash=item3b1620622f:g:XcsAAOSwxZNbV4Gu
McGrad sell older style 12mm nuts through aftermarket suppliers. They are good but the hardest to beat I've ever come up against was Peugeot lock nuts. But they both usually end up in wet rags and the mig on high.
